Incoming call rejects by all Apps (iOS, Android, MAC, Windows)

[Evgeniy L.]

Hello everyone
Incoming call drops an attempt to ring to app and redirect to voice mail as rejected call. Iv no voicemail enabled, then call simply drops as busy.
Reproduces for Android, iOS, MacOS and windows clients.
Outgoing calls from apps works fine.
Desk phones (cisco and Yealink) receives calls normally only in case extension have no App provisioned.
issue started with 3cx 16.0.4 on Debian 9 (it's better to say spotted, due to nobody used apps before COVID-19 remote working case accured)
Upgrade to 16.0.5.611 changed nothing.

Here is verbose log for the case:

Hi Evgeniy

Please provide us with some basic info as per this post:
https://www.3cx.com/community/threads/information-to-provide-when-requesting-help.67558/

I would also recommend to make a brand new extension (don't change any settings please - leave all default) and provision it to a mobile app on your phone. Once provisioned, call the new extension from your deskphone and see if it rings.

 

[Evgeniy L.]

Dear John,

As I mentioned above:
3CX is 16.0.5.611
Server OS: Debian 9
On-premise dedicated server.
issue reproduces on ext to ext calls (and on incoming calls from PSTNs too)
Issue was reproduced with newly provisioned extensions and logs collected for initial post.
Android App tested 16.2.0.93
iOS App was latst available from AppStore today (sorry, have no iPhone near by)
3cx for MacOS 16.0.1.0
Web client of 16.0.5.611
Apps provisioned with tunnel over 5090 port.
We have Bridge trunks working fine in both directions over same 5090 port, so no firewall issues there expected.
Also outgoing calls from Apps going fine to other branch ot to other extensions with desk phones only.

I hope this helps.

PS: sometmes app rings once and rejects call to voicemail, sometimes no any rings on app, just a notification about missed call comes immediately after call rejected to voicemail.

 

[JohnS_3CX]

Can you also try with a new extension please as I described above?

 

[illcsales]

3CX is16.0.612
Server Windows 10
On-premise dedicated server.

We can confirm this problem when app and yealink desk phone are assigned on same extension and app has been provisioned on android device.
The call is able to be answered on android device and does not ring desk phone.
We get Cause: 488 Not Acceptable Here/INVITE

Created test extension as requested with no desk phone and provisioned same android device with test extension.
We can call in and the desk phone is accessible through Digital assistant but DID fails.
We did try partialy availble here but that had no affect:

[JohnS_3CX]

@illcsales I think your case is different, the inverse of the above. You should start a separate thread.

 

[Evgeniy L.]

Can you also try with a new extension please as I described above?

Dear John,
The test done and log provided with newly created extensions (you can notice "Test User " mentioned in logs)
I've created few more extensions - results and logs text are the same.

 

[JohnS_3CX]

Thanks Evgeniy, can you also now check with the Webclient now?

This should tell us where to look next.
